BACKGROUND Actinomycosis is a rare bacterial infection caused by Actinomyces. The symptom of actinomycosis is nonspecific and radiological images present as a slow-progressive mass lesion similarly to malignancies. Thus, it is difficult to distinguish pulmonary actinomycosis from malignancies. CASE PRESENTATION A 74-year-old male who had esophageal cancer and a pulmonary mass that was positiv...

Actinomycosis can involve all parts of the urogenital system. Urachal actinomycosis rarely reported and was mistaken with urachal adenocarcinoma. We report a case of urachal actinomycosis that presented with abdominal pain and underwent laparotomy with the diagnosis of urachal malignancy pathology reviewed the diagnosis of urachal actinomycosis. Patient had no problem in two years follow up.

Actinomycosis is a slowly progressive infection caused by anaerobic bacteria, primarily from the genus Actinomyces. Primary actinomycosis of the breast is rare and presents as a mass like density which can mimic malignancy. Mammography, ultrasonography and histopathologic examination is required for diagnosis. Treatment should consist of high doses of antibacterials for a prolonged period of ti...

Primary cutaneous actinomycosis is very uncommon. We report a patient with cutaneous actinomycosis with multiple lesions without any detectable extra-cutaneous lesions. In our patient the actinomycosis was the presenting manifestation of HIV infection.

Abdominal actinomycosis is extremely rare. We report a case of actinomycosis of the small intestine presenting as a perforation and requiring subsequent laparotomy and small bowel resection. Such a description of actinomycosis has not previously been described in the literature.

BACKGROUND Pulmonary actinomycosis is a chronic pulmonary infection caused by Actinomyces. Both improving oral hygiene and early application of antibiotics to the case of suspicious pulmonary infections result in changes in incidences and presentations of pulmonary actinomycosis. However, there are little reports dealt with the recent clinical characteristics of pulmonary actinomycosis. This st...

live in the mouth, gut and female genitalia. Actinomycetes are gram-positive filamentous bacteria rather than fungi, as is sometimes assumed (1). The first case of actinomycosis in a human was reported by Lebert in 1857 (1). Despite the frequency of actinomycosis, spinal actinomycosis is rarely encountered. In this report we describe the computed tomography (CT) and magnetic resonance (MR) imag...

Mycobacterium abscessus is a rapid grower, can cause pulmonary infection and cutaneous infection. They are usually resistant to multiple antimicrobials. So challenging physicians for treatment. Here we report a rare case of caused by mimicking actinomycosis. Keywords: Actinomycosis cutaneous infection, Mycobacterium NTM.

Actinomycosis is a chronic, suppurative, bacterial disease characterized by extensive fibrosis, occasional granulomas, abscess formation, and sinus discharge containing sulfur granules. In actinomycosis, the CNS is involved in only 3.3% of cases [1]. This report documents an actinomycotic granuloma simulating a trigeminal neuroma clinically, radiologically, and surgically. It is also the first ...

11 Sum mary Actinomycosis is a rare soft tissue infection caused by Gram-positive, anaerobic bacteria. It is rarely seen in childhood. However, most of the cases are misdiagnosed. Thus, the true prevalence cannot be estimated. The major clinical forms of actinomycosis are; cervicofacial, thoracic, abdominal and pelvic forms. The most frequent clinical form is cervicofacial actinomycosis. Diagno...
